D( q )
q = 0
q = 0
q = 0
q in (-oo:0) U (0:+oo)
8/q-((3/2)*q) = 0
(-3/2)*q+8/q = 0
8*q^-1-3/2*q^1 = 0
(8*q^0-3/2*q^2)/(q^1) = 0 // * q^2
q^1*(8*q^0-3/2*q^2) = 0
q^1
(-3/2)*q^2+8 = 0
(-3/2)*q^2+8 = 0
DELTA = 0^2-(4*8*(-3/2))
DELTA = 48
DELTA > 0
q = (48^(1/2)+0)/(2*(-3/2)) or q = (0-48^(1/2))/(2*(-3/2))
q = (4*3^(1/2))/(-3) or q = (-4*3^(1/2))/(-3)
q in { (4*3^(1/2))/(-3), (-4*3^(1/2))/(-3)}
q in { (4*3^(1/2))/(-3), (-4*3^(1/2))/(-3) }
